Simulation shows how the coronavirus can spread in supermarkets

Boston Herald headline news today (4/10/2020)! How irresponsible journalism feeds the mass panic and hysteria!

Many questions arise, the journalist of the article did not answer:

1. You can simulate with a computer almost anything you like! How accurate or realistic is this simulation? Was the simulation validated by empirical research?
2. Was this only a worst case scenario that this article presents?
3. Was this shocking image of the simulation necessary or even representative of the study?
4. Is this really a new result ("Droplets from a single cough remain in the air for several minutes") or does this not apply to any common cold or influenza? If yes, why should we be worried now, because of SARS-Cov-19?
